This data set is from a series of laboratory experiments examining the interactions between red and blue king crabs and habitat. We examined how density and predator presence affect habitat choice by red and blue king crabs. Further experiments determined how temperature and habitat affect predation by year-1 red king crab on year-0 blue king crab. Finally, long-term interaction experiments examined how habitat and density affected growth, survival, and intra-guild interactions between red and blue king crab.

In 1995, an area of the seafloor near Salisbury Sound was trawled to identify immediate effects on large, erect sponges and sea whips. Video transects were made in the trawled areas, as well as in reference areas with a manned submersible. One year later, the video transects were repeated to characterize medium-term survival and recovery of the sponges and sea whips. In 2009, the site was revisted to document the long-term effects of trawling. Thirteen years after trawling, the incidence of damage to sponges and sea whips in the trawled areas was higher than in the reference areas. Sponge density was also lower in the trawled areas.

This is data from a long-term monitoring project which utilized sonic tags to follow aggregations of red king crab in Womens Bay near Kodiak Alaska. The database consists of four major tables: Sonic tags: An inventory of all tags used recording crab size and sex dates of tag release and recovery, and if possible the reason for tag loss. Locations: Field locations in latitude, longitude, and depth for sonic tags, generally acquired on a weekly basis. Dive summary:A summary of dive observations on sonic tagged crab aggregations to document crab behavior and habitat use. Crab measurements:Measurements of crab carapace lengths, sex, and shell conditions of diver-collected crab from crab aggregations associated with tagged crab.

This dataset contains data from a series of experiments that determined the upper thermal tolerance of early benthic stage red and blue king crabs. Experiments included determining the temperature at which 50% of crabs died after 24 hour exposure, determining the effect of temperature on feeding ration, and the effects of temperature on long-term growth and mortality.
